1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundPostoperative nausea and vomiting (PONV) is a common complication after thyroidectomy. Steroids effectively reduce nausea, pain, and inflammation; therefore, preoperative administration of steroids ought to improve these surgical outcomes.

methodsWe conducted a systematic review of randomized controlled trials (RCTs) that compared preoperative single-dose administration of dexamethasone with no dexamethasone in patients undergoing thyroidectomy. The primary outcome was occurrence of PONV within 24 h, and the secondary outcomes were pain, use of analgesics, and steroid-related complications.

resultsFive RCTs were included with a total of 497 patients. A statistically and clinically significant difference in the incidence of PONV was found in favor of dexamethasone [relative risk (RR) 0.38; 95% confidence interval (CI) 0.30-0.49). The visual analog pain score was significantly diminished (weighted mean difference, WMD)-1.50; 95% CI-2.54 to -0.46) at 24 h. The incidence of analgesics use was also reduced (RR 0.61; 95% CI 0.41-0.90) in the dexamethasone group. No steroid-related complications were noted.

conclusionsA single preoperative administration of dexamethasone reduced the incidence of PONV and analgesic requirements in patients undergoing thyroidectomy. Prophylactic use of steroids for patients undergoing thyroidectomy is safe and should be considered for routine clinical practice.
